Another popular variety - Wisley Primrose has soft, primrose-yellow flowers which gives a softer, less garish effect than some of the hotter colours. The foliage, long and narrow, is often pale at the tips on spring growth but normally mid-green and greyish. 25cm (10") high.
When trimmed after flowering (as you should with all Rock Roses - it isn't essential, but it promotes further flowers) Wisley Primrose bushes up well and stays neat. And it has an AGM to prove it's worth.
